Timelines
The history of Earth is divided into four great eons. Each eon saw the most significant changes in Earth's composition, climate, and life. Each eon is subsequently divided into eras, which in turn are divided into periods, which are further divided into epochs.
For the sake of clarity, brevity, or some other reason, certain details or events may not be included in this timeline. If you'd like to know more about this topic, a good place to start would be the timeline's primary source of information. You can also follow the links within the slides for further details.
